springJDBC核心知识点

 1：可返回对象。

   String selSql=" select trade_id, subject, descption, medical_his, check_result, hope_help, accept_time, doctor_id,doctor_name, pay_fee, order_status, pay_start_time, pay_finish_time, pay_id, status, remark from td_trade_advise_fee where trade_id= "+ tradeId;

TradeAdviseFee tradeAdviseFee=(TradeAdviseFee)this.jdbcTemplate.queryForObject(selSql,new dviseFeeRowMapper());

return tradeAdviseFee ;

---

2：查询：

public long getPayQuestionCount(String userId, int status) {

             String tempSql = "select count(1) from td_trade_advise_fee adviseFee where 1=1"; 

             if(userId!=null && !userId.equals("")){

                 tempSql += " and adviseFee.doctor_id='"+userId+"'"; 

                     }

             tempSql+="and                         

            adviseFee.status='"+6+"'";

             long count = this.jdbcTemplate.queryForLong(tempSql); 

             return count;

 }

3：更新

@Override

public int updateWZTradeAdviseFee(TradeAdviseFee tradeAdviseFee) {

// TODO Auto-generated method stub

String updateSql = "update td_trade_advise_fee set subject=?,descption=?,medical_his=?,check_result=?,hope_help=?,doctor_id=?,doctor_name=?," +

"pay_fee=?,status=?,patientName=? where trade_id=?";

int result = this.jdbcTemplate.update(updateSql, new Object[]{tradeAdviseFee.getSubject(),tradeAdviseFee.getDescption(),tradeAdviseFee.getMedicalHis(),

tradeAdviseFee.getCheckResult(),tradeAdviseFee.getHopeHelp(),tradeAdviseFee.getDoctorId(),tradeAdviseFee.getDoctorName(),tradeAdviseFee.getPayFee(),

tradeAdviseFee.getStatus(),tradeAdviseFee.getPatientName(),tradeAdviseFee.getTradeId()});

return result;

}

---

4:查询list集合

public List<Long> getTradeAdviseDoctorPager(String userId, Pager pager) {

String tempSql = "select distinct(adviseFee.doctor_id) from td_trade_advise_fee adviseFee,td_trade trade where adviseFee.trade_id=trade.trade_id and trade.user_id=?";

String selectSql = "select * from (select * from " + tempSql + ") as a limit ?,?";

List<Long> doctIdList = this.jdbcTemplate.queryForList(selectSql, Long.class, new Object[]{userId});

return doctIdList;

}

---

5：删除

public int deleteTradeAdviseFee(long tradeId) {

String deleteSql = "delete from td_trade_advise_fee where trade_id=?";

int result = this.jdbcTemplate.update(deleteSql, new Object[]{tradeId});

return result;

}

---

6：插入

public boolean insertTradeAdviseFee(String cookieId, long tradeType, String tradeName, 

String userId, String userName, TradeAdviseFee tradeAdviseFee) {

try {

String getSeqSql = "select max(trade_id)+1 from td_trade_advise_fee";

long newSeq = this.jdbcTemplate.queryForLong(getSeqSql);

Date da=new Date();

String insertTradeSql = "insert into td_trade(trade_id,cookieId,trade_type,trade_name,user_id,user_name,start_time,state)" +

"values(?,?,?,?,?,?,"+da+",1)";

int result = this.jdbcTemplate.update(insertTradeSql, new Object[]{newSeq,cookieId,tradeType,tradeName,userId,userName});

String insertAdviseSql = "insert into td_trade_advise_fee(trade_id,subject,descption,medical_his,check_result,hope_help,accept_time," +

"doctor_id,doctor_name,pay_fee,order_status,status)values(?,?,?,?,?,?,"+da+",?,?,?,?,?)";

result = this.jdbcTemplate.update(insertAdviseSql, new Object[]{newSeq,tradeAdviseFee.getSubject(),tradeAdviseFee.getDescption(),tradeAdviseFee.getMedicalHis(),

tradeAdviseFee.getCheckResult(),tradeAdviseFee.getHopeHelp(),tradeAdviseFee.getDoctorId(),tradeAdviseFee.getDoctorName(),tradeAdviseFee.getPayFee(),});

return true;

} 

catch (DataAccessException e) {

logger.error("添加收费咨询信息错误!", e);

}

return false;
